Worth watching.

I was quite skeptical before watching this drama after reading so many comments about how it gets boring after few episodes but I'm glad I watched
it since I totally enjoyed watching it. I was hooked to this drama throughout the 16 eps. Also it was my first ever Ji Chang-Wook drama and oh boy what great acting skills he has...Completely fell for him!!! Storyline was great too. Even the action scenes were good. If anyone is in doubt before watching this drama I would suggest them to give it a shot..you won't be disappointed.
